Application filed September 16, 1918. Serial No. 254,216.

To all whom-it may concern:

Be it known that I, RAY P. JAoxsoN, a citizen of the United States, and a resident of Edgewood Park, in the county of Allegheny and State of Pennsyl'vania, have invented a new and useful Improvementin Insulators, of which the following is a specification.

h'ly invention relates to strain insulators and particularly to connecting means there'- for.

One object of my invention is to provide a device ofthe above-indicated character that shall facilitate the assembly and disassembly thereof by hand manipulation...

Another object of my invention. is to provide a flexible conductor for a strain insulator that, in operative position, shall be securely engaged in wedging relation to asimilar member. p

A further object of my invention is to provide a connector embodying substantiallyaligned longitudinal cooperating members having enlarged overlapping ends and means disposed intermediate said ends for preventing separationthereof in the direction of each other.

In practicing my plurality of relatively-short flexible cables,

each of substantially U-shape, having the curved portions thereof disposed loosely in an, aperture in an insulating member or other device and enlargedends on the legs that project from the 'member with which they are associated. Thesev ends are each respectively paired with the ends of a similar cable,'thereby forming a substan--' tially continuous loop, with the respectively correlated enlarged ends slightly overlap- 40 ping each other. A holding member embraces each of the cables, intermediate the overlapping ends, to wedgingly engage the same in operative position and permit a relatively"quick assembly'and disassembly' of the insulator.

Fig. 1 of the accompanying drawings is a fragmentary side-elevational view of a series or chain insulator embodying my invention; Fig. 2 is a detail view taken at right angles to Fig. 1, of a holding member embodying my-invention; Fig. 3is a detail view, similar to Fig. 2, of a modified form of holding member; and Fig.4 is a detail view showing the relation that -may be 4 assumed in operative position by certain invention, I provide a portions of an insulator connector embodymg my lnvention.

A series or chain insulator 1 comprises a apertures 3 for the loose reception of relatively-short cables or other flexible members 4. Each member 2 may be provided with two of the flexible members 4 that interlink and "extend outwardly in opposite directions to meet the ends of a pair of similar members 4 projecting from the next ad jacent member 2 or other device. Portions 5 of ball or other shape, and constituting enlarged ends of the members 4, are respecy tively paired with similar portions of the next adjacent memben 4 and engage the latter in slightly overlapping relation, being maintained in, this relation by a holding ASSIGNOR r0 WESTINGHOUSE member 6 that closely embraces each of the hollow frame having a relatively large central recess 7 communicating, through channels 8, with recesses 9 for the reception of the members 4. In assembling the insulator 1, the enlarged ends 5 are inserted through the recess 7 and moved transversely through the channels 8 into the recesses 9, whereupon the members 4 and 5 may assume the positions indicated in Fig. 4. The recesses 9 may be slightly larger than twice the cross sectional areaof the member 4 to receive two of such members and to permit the desired co-operative relation betweeneach of them and the adjacent'portion 5 of the other. As the channels 8 will permit the passage of only one of the members 4 at one time, the parts may not be readily separated except by hand-manipulation. In Fig. 3 a modification of the member 6 is shown, the central aperture member 7 being omitted 7 and the recesses 9 being accessible from the outer ends of the member 6.

When in operative. position, the members 4, 5 .and 6 are wedgingly engaged with respect to each other to provide secure con- -nectionbetween the members 2 or between one of themembers 2 and another device,

such as a conductor or supporting member.

When it is desired to replace an. injured member 2 or disassemble the insulator 1, a

slight contraction of the insulator, by which the tension thereof is relieved, permits the ready and quick hand-manipulation of the members 4 in removing them from the recesses 9.

While I have shown and described particular forms of my invention, changes may be effected therein without departing from the spirit and scope thereof, as set forthin the appended claims.

' I claim as my invention:

1. A connector comprising two elongated members to be connected and having enlarged overlappingends provided thereon before the connection thereof, and a connecting member for disposition between said ends and having an opening which receives and.' embraces said members with the enlarged head of each held against the side of the other.

2. A connector comprising two elongated members to be connected and having ena recess for the reception of both said members and an entrance to said recess to admit the members to the recess one at a time only.

4. A connector comprising two flexible members of U-shape arranged as a continuous loop and having two pairs of enlarged overlapping ends, and a holding member having a portion disposed between the overlapping enlarged ends of each pairthereof, said holding member having two openings each of such shape and size as toreceive a portion of each flexible member and to prevent the passage therethrough of the enlarged ends and an entrance to each of'said openope-nings one at a time only.

5. A connector comprising two flexible members of U-shape arranged as a continuous loop and having two pairs of enlarged overlapping ends, I and a holding member having a portion disposed between the overlapping enlarged ends ofeach pair thereof, said holding member havin a central recess of larger diameter than sa1d enlarged ends and two openings communicating with the recess, each of such shape and size as to receive a portion of each flexible member and to prevent the withdrawal therethrough of the enlarged ends, said holding member also having an entrance to each of said openings to admit the flexible members to the open ings one at a time only.

In testimony whereof, I have hereunto subscribed my name this 27th day of August,

RAY P. JACKSON.
